Understanding Power Loss at Altitude
At 5,000 feet, internal combustion engines lose about 15-20% of their rated power due to lower oxygen density. This means a generator rated for 2,200 watts at sea level may only deliver around 1,760-1,870 watts at altitude. When choosing a generator for high-altitude RVing, consider models with a higher rated wattage than your immediate needs to compensate for this loss. For example, the WEN GN5602X’s 4,500 running watts at sea level would still provide roughly 3,600-3,825 watts at 5,000 feet, enough for most RV appliances.
Inverter vs. Conventional Generators
Inverter generators like the Honda EU2200iTAN and Westinghouse iGen2800 produce cleaner power with less than 3% total harmonic distortion, making them safe for sensitive electronics like laptops and CPAP machines. They are also quieter and more fuel-efficient. Conventional generators like the WEN GN5602X are often more powerful for the price but are noisier and produce less stable power. For RV use, an inverter generator is generally recommended.
Key Features for RV Use
Look for features like RV-ready outlets (TT-30R), electric start, and carbon monoxide shutdown sensors for safety. The WEN GN5602X includes all these plus a wheel kit for easier mobility. The Honda and Westinghouse models offer parallel capability, allowing you to combine two units for double the power. For more on RV-specific generators, see our guide on best generators for large RV.
